48-bit computing: Difference between revisions

Addressing: Split the IMPI (S/38, CISC AS/400) stuff from the block addressing stuff. S/38 only had the CISC IMPI; AS/400 had both IMPI and PowerAS RISC. Just say they used 48-bit addresses.
Addressing: The computer on which I'm typing this has at least two MAC addresses (Wi-Fi and Bluetooth); servers might, for example, have several Ethernet adapters. MAC addresses are a property of NICs, not computers.
Line 14:
The minimal implementation of the [[x86-64]] architecture provides 48-bit addressing encoded into 64 bits; future versions of the architecture can expand this without breaking properly written applications.
 
The media access control address ([[MAC address]]) of a computer[[network interface controller]] uses a 48-bit address space.
